Summary
Collaborative model-driven development faces synchronization challenges. This study introduces reactive links to automatically propagate changes across diverse engineering models and tools, enhancing consistency and efficiency.
Area of Science:
- Software Engineering
- Systems Engineering
- Computer Science
Background:
- Collaborative model-driven development is crucial for complex systems.
- Maintaining model consistency across tools and domains is challenging.
- Existing solutions require manual change propagation, lacking efficiency.
Purpose of the Study:
- To introduce a novel solution for automatic change propagation in collaborative model-driven development.
- To address limitations in traceability and efficiency of current methods.
- To ensure synchronization and consistency of model artifacts across different domains and tools.
Main Methods:
- Developed a solution based on highly granular trace links called 'reactive links'.
- Reactive links automatically propagate property value changes between models in different domains and tools.
- Evaluated the solution's feasibility, performance, and flexibility in practical scenarios.
Main Results:
- The reactive links successfully resolved all required change propagation cases.
- Demonstrated significant efficiency improvements compared to manual propagation.
- Validated the solution in three practical scenarios from two partner organizations.
Conclusions:
- Reactive links enhance the engineering of software-intensive systems.
- The solution reduces the manual burden of keeping models synchronized.
- It effectively avoids inconsistencies arising from collaborative, multi-domain engineering.

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

967
A coplanar force system refers to a set of forces that all lie in the same plane and are subject to different reactions between the point of contact and the supports. Understanding how different types of supports affect coplanar forces is crucial for designing safe and reliable structures that can withstand external loads.
The purpose of the supports is to prevent the translational motion of the system by applying an equal and opposite force and to prevent the system's rotation by applying...

Support reactions in three dimensions help maintain the stability and equilibrium of various structures and systems. These reactions prevent the system from translating and rotating, ensuring the design can withstand external forces and perform its intended function efficiently and safely. Some of the supports providing support reactions in three dimensions are discussed below:
Ball and Socket Joint is one of the supports allowing free rotation about any axis. This freedom of rotation is...

166
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

01:11Radical Reactivity: Overview
2.2K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...
